Staples Inc. has launched an online ink and toner recycling program.

The Framingham, Mass.-based office supply company said in a news release the program is an expansion of the existing, in-store Staples Rewards ink and toner recycling program.

Through the online program Staples Rewards members can recycle empty ink and toner cartridges by printing a pre-paid shipping label to send their cartridges in for recycling and receive $2 back in Staples Rewards for each.

Staples said it is launching the program to make a positive impact on the environment and to meet the needs of its customers.

The company has recycled 350 million ink and toner cartridges since 2005, averaging more than 60 million cartridges per year in the past three years. Through the cartridge recycling program, Staples has recycled 182 million pounds of plastics and metals.

The retailer’s in-store electronics recycling program has a goal of recycling 40 million pounds of e-waste globally each year by 2020. Since 2007, Staples has recycled 64 million pounds of electronic waste.
